Abstract

Un mécanisme d'entraînement de lame est fourni, qui permet le mouvement réciproque sélectif d'une lame de découpe de tissu placée à une extrémité distale d'un assemblage de trocart optique pour permettre de passer d'une position non déployée à une position déployée puis à nouveau à une position non déployée. Le trocart a un obturateur optique qui comprend un manchon ayant un alésage longitudinal entre une extrémité proximale et une extrémité distale. L'alésage longitudinal du manchon est configuré pour recevoir au moins une partie d'un endoscope ou un système de transfert d'image similaire. Un élément optique à objectif, tel qu'une fenêtre optique, est placé à l'extrémité distale du manchon et est fourni pour permettre aux images optiques de passer dans le trou longitudinal du manchon et pour permettre à la lumière d'éclairage de passer sur le champ opératoire.
